Search verified manufacturers from inside Claude or ChatGPT.

SupplySpark exposes its supplier database as an MCP server and a REST API. Ask your assistant for "GOTS-certified hoodie manufacturers in Turkey under 300 MOQ" and it searches SupplySpark directly — MOQs, lead times, certifications, evidence, and a profile link for every result. The assistant gets a preview of the top 5 per search with total counts, and every result links to the complete profile on supplyspark.co, where the full ranked list is free to read. Contact details and exports need a free account.
